Here we go again …

Recently there has been a major comments war on Amerika.org regarding the website moderator’s take on one of my posts which I published a few weeks ago. Dare I import the war onto my own blog? Apparently, I am insane enough to do this.

Do the Irish have “negroid” admixture?

(The following map includes both Sub-Saharan and North African components)

African-admixture

Apparently not [the data for this map gives 0% African admixture to the Irish].

West Asian (Northern Middle Eastern) admixture?

West-Asian-admixture

It is found at low frequencies throughout Northwestern Europe.

Admixture related to Semitic peoples?

Southwest-Asian-admixture

There is a small amount in all Europeans except for a few Eastern Europeans, the Saami, Finns, Basques, and Catalans.

Martian admixture? (someone actually suggested this!)

Give me a break.

So what makes the Irish a little bit different from the English, and pulled slightly in the same direction as Iberians are on a genetic principal component analysis?

A bit more Atlantic admixture (combination of Neolithic farmer and Mesolithic hunter-gatherer) most likely from the Megalithic period is responsible for this. The Irish have more than the English, but the English have some of this admixture as well. It peaks in the Basques, is relatively high in Eastern Iberia and the “Celtic Fringe”, followed by other geographically Western European populations, but is much lower in the Eastern Mediterranean, Near East, and Northern Africa.

Atlantic-admixture

This admixture peaks in the Basque population and appears to be a blend of Near Eastern Neolithic farmers and Mesolithic European Hunter-Gatherers. It matches mostly the extent of the Atlantic Megalithic culture. Several ancient samples were added to GEDMatch and analysed with Eurogenes K15. Nine Megalithic Iberian samples (3211-1518 BCE) had an average Atlantic percentage of 38.8%, similar to modern Basques. Three samples from the Remedello culture in Late Neolithic northern Italy (3483-1773 BCE) scored an average of 35.2%, considerably more than modern Italians, even Sardinians. One Megalithic Irish sample from Ballynahatty had 32.7% of Atlantic, about the same as modern Irish people. (source)

If you don’t like these admixture maps, then go argue with Maciamo Hay on Eupedia about them. I have my own life to live.
